摘要： A printer is described having a control unit and/or image processor to determine a number of pixels by which to scale an image along an axis of the image, wherein, the scaling of the image is less than 10% of the image along the axis. The control unit and/or image processor is also to identify locations along the axis equal to the number. The control unit and/or image processor is also to remove a region of more than one pixel along the axis at each of the locations. The control unit and/or image processor is also to insert a region of more than one pixel along the axis at each of the locations, where, a difference between pixels removed and pixels inserted accounts for the number.

摘要： A method is described that entails printing a series of test patterns. Each test pattern has its own respective set of outer lines and set of inner lines. The series of test patterns have a different intended spacing between their respective inner lines and outer lines. The intended spacing of each test pattern is printed in a manner that correlates the intended spacing of each test pattern with its test pattern. Each of the outer lines are printed with a first print source and each of the inner lines printed with a second print source. Inner lines of a first set of the test patterns are shorter than inner lines of a second set of the test patterns to enhance resolution at which differences in the spacings between respective inner and outer lines of same test patterns are able to be detected across different test patterns.
摘要翻译：描述了需要打印一系列测试图案的方法。每个测试图案都有自己各自的外线和内线组。一系列测试图案在它们各自的内线和外线之间具有不同的预期间距。每个测试图案的预期间距以将每个测试图案的预期间距与其测试图案相关联的方式打印。每个外线都印有第一打印源，每条内线印有第二打印源。第一组测试图案的内线比第二组测试图案的内线短，以增强能够在不同测试中检测相同测试图案的相应内外线之间的间隔的差异的分辨率模式。

摘要： Methods and systems herein provide for reducing artifacts during printing. One printing system is operable to prepare a continuous tone image (CTI) for printing onto a print medium by generating an initial half tone image (HTI) based on the CTI. The printing system includes a printer and a print controller. The print controller filters the initial HTI and the CTI with a perceptual filter and determines an error between the filtered CTI and the filtered HTI. The print controller prints the HTI via the printer to determine printer artifacts and processes a scanned version of the printed HTI to determine an error between the filtered CTI and the scanned and filtered HTI. This processing updates the initial HTI and reduces the error between the filtered CTI and the filtered HTI.

摘要： The systems and methods presented herein provide for calibrating a print engine of a printing system. The printing system prints image data on a print medium and scans the printed image data. Color values of the scanned image data are then measured and various tints of color values and their transition locations are identified. A calibration module estimates the original optical densities of the identified color value tints and generates a target optical density for each of the identified color value tints using the estimated original optical densities to determine print irregularities in the color values of the scanned image data. The calibration module then generates a halftone screen based on the mean optical densities and applies the generated halftone screen to the print engine to calibrate the print engine.
